17:10 {5} So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
(5) No matter how perfectly we may keep the law, it deserves no reward.
17:10 We are unprofitable servants. Our Master owes us no thanks when we serve him faithfully, for we have only done our duty. The heavenly reward to the faithful is of grace, not of debt (Ro 11:6).
17:10 When ye have done all, say, We are unprofitable servants - For a man cannot profit God. Happy is he who judges himself an unprofitable servant: miserable is he whom God pronounces such. But though we are unprofitable to him, our serving him is not unprofitable to us. For he is pleased to give by his grace a value to our good works, which in consequence of his promise entitles us to an eternal reward.
17:1-10 It is no abatement of their guilt by whom an offence comes, nor will it lessen their punishment that offences will come. Faith in God's pardoning mercy, will enable us to get over the greatest difficulties in the way of forgiving our brethren. As with God nothing is impossible, so all things are possible to him that can believe. Our Lord showed his disciples their need of deep humility. The Lord has such a property in every creature, as no man can have in another; he cannot be in debt to them for their services, nor do they deserve any return from him.
